Specification of Letters Patent.

Patented Oct. 7, 1919.

Application tiled .Tune 26, 1919. Serial No. 306,834.

To all 'whom t may concern.'

Be it known that I, CHARLES KRO-Neonati citizen of the United States, resi `ing at Chicago, in the county of Cook and. tateef Illinois, have invented certain new vand useful Improvements in Trace Construction; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to harness traces and tugs, and is particularly an iinprovement over the harness trace disclosed in patent granted to F. W. Hodges, under date of July 10, 1917, No. 1,233,288.

This invention has for its object the improvement of the terminal blocks of the trace or tug for more efficiently connecting the cable and covering of the trace with the end links or couplin s.

A further obJect of the invention is the provision of a terminal block having improved lneans for engagement with the covering or strap of the trace, in order to render the construction more substantial, and to also make the joint Waterproof.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described 4and claimed, it being understood that changes can be made within the scope of what is claimed without departin from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:-

Figure 1 is an elevation of the improved trace or tug, portions being broken away and shown in section.

Fig. 2 is a side elevation of one of the improved terminal blocks, constituting an article of manufacture.

Fig. 3 is a cross section taken on the line 3 3 of Fig. 1.

The trace, like that disclosed in said patent, embodies a flexible cable 2 of endless formation, and embodying a pair of parallel longitudinal portions connected at their opposite ends by loops. A covering or strap 3 of leather or other suitable material extends longitudinally along the cable 2 at one side thereof, and has its edge portions bent around the longitudinal portions of the cable and brought together between them, as seen in Fig. 8, and a strip 4 of leather or other suitable material overlaps the edges of the covering 3, and said strip and edges of the covering are stitched or otherwise secured to the intermediate portion of the covering, thereby securing the strip, covering and cable together so as to constitute the trace 1. The end loops of the cable project beyond the ends of the covering for engagement with the terminal blocks 5 of the trace, and said blocks are hingedly connected with the end links or couplings G by means of U-shaped clips or straps 7, the bends of which extend around the links 6, and the terminals of which extend along and overlap the blocks 5 and opposite sides of the covering 3. Rivets 8, extend through the clips 7 and blocks 5 to clamp them together, and rivets 9 extend through the clips and covering 3, in order to firmly secure the parts together. The edges of the blocks 5 which engage the links 6 are preferably grooved, as at 10, to hingedly engage the links 6 with the clips 7, thereby permitting said links to swing or turn relatively to the trace. Each block 5 is provided at one side with a U-shaped groove 11, the terminals of which extend to that edge of the block opposite to the grooved edge 10, and one loop of the cable 2 is adapted to lit in said groove 11 to connect the cable and block. The block 5 has an aperture 12 located within the groove, that is, Within the area surrounded by the groove, and the rivet 8 extends through the aperture 12 to clamp the clip 7 over the groove 11 for holding the loop of the cable therein.

The construction as above described is substantially the same as disclosed in said patent, and in order to enhance the eiliciency and utili-ty of the terminal blocks 5, they have been provided with improvements as will be presently described.

Thus, that edge of the block 5, against which the covering 3 abuts, is provided with extensions 13 adjacent to and outside of the ends of the groove 11, and said extensions 13 are provided with recesses or notches 14 at their inner sides, so that said extensions are of arcuate or concaved cross sections to lit snugly over the rounded edge portions of the covering 3, and said recesses provide abutments 15 at the ends of the groove 11 against which the ends of the covering 3 abut. These extensions 15 will extend for a short distance along the edges of the covering 3 and will fit partially around the edge portions of the covering where they extend around the cable, and the eide portions of the corresponding clip 7 will overlap the extension 13, thus providing a waterproof eonnee'tion between the covering and terlninal bleek. In this manner, the end of the covering extends between and within the extensions 15, so as to keep ont water from between abutting portions ot the covering and terminal block.

Another feature of the construction is the provision of a tongue 1.6 extending from that edge of block 5, having the extensions 15, said tongue extending from the block between the ends of the groove 11 and at that side of the block opposite to the side having said groove. This tongue 16 will extend alon that side of the covering 3 opposite to the e ip 4, as seen in Fig. 3, and is provided with an aperture 17 for the passage of the nearest rivet 9. This tongue in being riveted io the Covering in Connection with the 0X- tensions 15 fitting over the covering will provide a more substantial and effective connection between the trace proper and termina] block.

Having thus described the invention, what is claimed as new is 1. A terminal bloek for a trace having a U-shaped groove in one side with its ends extending to one edge, Sai d edge of .the blOCk having eoncaved extensions outside 0f th? ends of .laid groove to Iit over the edgeS 0f a covering abutting said edge.

2. A terminal bleek for a trace having a U-el'laped groove in one side with its ends extendin to one edge of the block, said edge of the b ook having a tongue extending therefrom between Said groove ends and pro; vided with means for attachment to a trace.

3. A terminal block for a. trace having a Usha ed groove in one side with its ends exten ing to one edge of the block to re eeve a terminal loop or' a trace, said edge of the block having eoneaved extensions at the outer sides of the ends of the groove to fit over the edges of a covering abutting said edge of the block, and said edge of the block being further provided with a tongue extending therefrom between ihe ends ol" the groove and provided with n'ieans vtor attach ment to said covering.

In testimony whereof I have signed in'v name to this specification in the preSenr-e oi two subscribing witnesses.
